Characteristics of Fields Flashcard

Front

What is the relationship between distance from a field's source and the force on an object?

Back

The farther the object, the weaker the force.

Front

What is the strength of the magnetic force at a distance of 1.00 m from the magnet?

Back

100.0 N.

Front

What is the effect of using the same modeling method for all fields?

Back

It fails to represent differences.

Front

What is a characteristic of a contact force?

Back

It can only be exerted in one direction at one time.

Front

What is the direction of Earth's magnetic field lines?

Back

From North to South.

Front

Define a field in physics.

Back

A field is a region of space characterized by a physical quantity at every point, such as gravitational or magnetic fields.

Front

What is a magnetic field?

Back

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.

Front

What is the difference between contact and non-contact forces?

Back

Contact forces require physical interaction between objects, while non-contact forces act at a distance without physical contact.

Front

Give an example of a non-contact force.

Back

Gravity is an example of a non-contact force.

Front

What happens to the strength of a magnetic field as you move away from the magnet?

Back

The strength of the magnetic field decreases as you move away from the magnet.
